Frequently Asked Questions
Common questions about single-phase pad-mounted transformers
What is a single-phase pad-mounted transformer?
A single-phase pad-mounted transformer is a ground-mounted distribution transformer housed in a tamper-resistant steel cabinet. It's designed for underground power distribution systems, providing single-phase power to residential, commercial, and light-industrial applications.
What are the main advantages of single-phase pad-mounted transformers?
Key advantages include: compact and space-efficient design, enhanced safety with lockable enclosures, aesthetic appeal for residential areas, protection from weather and vandalism, easy maintenance access, compatibility with underground cable systems, and reliable single-phase power distribution.
What voltage ratings are available?
Our single-phase pad-mounted transformers support high voltage up to 19.9 kV (150 kV BIL) and low voltage options including 120V, 240V, 480V in various configurations. Custom voltage specifications can be accommodated based on your requirements.
What capacity (kVA) options do you offer?
We manufacture single-phase pad-mounted transformers from 5 kVA up to 250 kVA. Common sizes include: 5, 10, 15, 25, 37.5, 50, 75, 100, 167, and 250 kVA. Custom capacities can be designed for specific applications.
What standards do your transformers comply with?
Our single-phase pad-mounted transformers comply with ANSI/IEEE standards including C57.12.00, C57.12.22, C57.12.26, and C57.12.28. They meet DOE 2016 energy efficiency standards and hold NEMA, UL, and CSA certifications.
What cooling types are available?
Standard cooling is oil-immersed (ONAN - Oil Natural Air Natural). We also offer optional FR3 bio-based dielectric fluid or high-flash-point mineral oil for enhanced fire safety and environmental protection.
What is the typical lead time for delivery?
Standard configurations typically have a lead time of 8-12 weeks. Custom specifications may require 12-16 weeks. We maintain inventory for common sizes to support urgent orders. Contact our sales team for specific delivery timelines.
What applications are single-phase transformers best suited for?
Ideal applications include: residential underground distribution, commercial buildings, EV charging stations, pump systems, street lighting, telecommunications facilities, and any single-phase power requirement from 5 kVA to 250 kVA.
